The correct answer is c) Rooftop solar installations.
The Soura project is a government initiative to promote rooftop solar installations in Kerala. The project aims to reduce the state’s dependence on fossil fuels and to promote renewable energy. The project offers subsidies and other incentives to homeowners who install rooftop solar panels.
Hydroelectric power is a type of renewable energy that uses the power of moving water to generate electricity. Wind power is another type of renewable energy that uses the power of the wind to generate electricity. Energy conservation is the practice of using less energy.
All of these options are important for reducing greenhouse gas emissions and promoting a sustainable future. However, the Soura project specifically focuses on rooftop solar installations.
